Corpus spongiosum - Definition

It is a lump of spongy tissue mass that is situated in the penis. It is composed of erectile tissue and is also bordered by Tunica albuginea. Multiple tissue of this form is referred to as “Corpora spongiosa”.

Corpus spongiosum – Other Names

Sometimes, this tissue mass is also referred to as “Corpus cavernosum urethrae,” a term that was earlier used to refer to this structure. It is also referred to by synonyms such as:

Corps spongieux du pénis

Corpus spongiosum penis

Spongiose body of penis

Spongiosum de la recopilación del pene

Corpus spongiosum - Location

The structure is situated in the lower part of the penis, in the groove positioned between the Corpora cavernosa.

Corpus spongiosum - Functions

The structure surrounds the urethra and prevents it from getting squeezed and closed while the penis is in an erect posture. Without this mass of tissue, the male urethra would have shut itself during erection. This would make it impossible for semen to pass smoothly through the penis during ejaculation.The Corpus spongiosum, as well as the Corpus cavernosum, get filled with blood and become larger and larger in size during an erection. The enlargement continues until the shaft gets stiff and hard.

Corpus spongiosum - Problems

A man may have problems in having an erection or experience arousal during physical intimacy due to damage to this structure. A disease known as Priapism (marked by painful and prolonged erection) may cause damage to the Corpus spongiosum. The structure may also suffer damage due to an injury to the penis.
